MACHINE FOR MAKING LAPS ON BELTING.

SPECIFICATION formingpart of Letters Patent No. 242,087 dated May 24,1881.

' Application filed March 28,1881. (N0 model.)

.To all whom it may concern:

Be it known that I, CHARLES H. WESTON, a citizen of the United States,residing at Yarmouth, in the county of Cumberland and State of Maine,have invented certain new and useful Improvementsin Machines forMakingLaps in Leather Belting and other Material; and I for making the'beveledportion upon either end of leather or other belting; and the noveltyconsists in the construction and arrangement of parts, as will be morefully hereinafter set forth, and specifically pointed out in the claims.

The object of the invention is to bevel each end of a strap or body ofleather, upon oppoe site sides in such a manner that the beveledportions, when placed together and secured, will present a portion wherethe lap occurs of approximately the same width and thickness as thebody, and to accomplish this by a single operation upon each end to savestock and to insure a perfect lap, a positive length, and eventhickness. Heretofore this has been ac complished by commencing thebevel at a proper point upon the body and cutting down toward the end;but in such operation not only is the thinner part or end liable tobreak off and prevent a perfect lap,'but it is necessary to trim theends by a subsequent operation, usually by hand. It is also difficult toobtain the exact starting-point upon the body of the material. In myinvention the point of commencementis arbitrary, being the extreme end.The beveled portions are exactly similar, and no subsequent operation isnecessary.

To this end the invention consists in the mechanisms constructed andarranged in relation to each other, as shown in the accompanyingdrawings, which form a part of this specification, and in which- Figure1 is a topplan view of the device Fig. 2, a central longitudinal sectionon as .10;

Fig. 3, a sectional view, showing a modification of the presser-bar;Fig. 4, a side view; Fig. 5, section on y y of Fig. 4.

Referring to' the drawings, A represents a proper frame havinglongitudinal slot a and journal-bearings a, t'orashaft,B,havingp0werpulley 1) upon one end, and a cam-wheel rigidly secured tothe other. This cam-wheel O is preferably made with an open corrugatedannular slot, 0, in which operates a pin, d, secured upon one end of alever, D, pivoted or fulcrumed at d upon a frame or bracket, 01 securedto the main frame A, the other end of the lever D being loosely securedto a reciprocating knife or saw, E, working in proper guides e in theframe A. This cam-wheel C may, however, be made with but one corrugatedside, and have a spring attached to hold the pin din contact therewithby a constant force.

Rigid upon the shaft B, at or near the center thereof, is a gear-wheel,F, which meshes with a rack-bar, G, secured upon the lower surface of areciprocating table, which works in guides of upon the inner sides ofthe frame A. For convenience I will describe this reciprocating table indetail.

H represents the body of the table, to which the rack-bar G is secured,to which is hinged, at h, the inclined table H, which is renderedadjustable at its free end by means of a cam or cams, I, rigid upon ashaft, 1, working in a transverse slot or bearing, 2', formed in thebody H, and having a thumbwvheel, i, or other convenient manipulatingdevice. The cams I operate upon the table H to elevate the free endthereof at the will of the operator. The

Y shaft 1 traverses the slot a, while the table is being reciprocated bymeans of the shaft B, and said slot serves, in a measure, to control thetable against vertical displacement.

A feed-roll, K, is journaled in blocks 70, op erating loosely inrecesses in standards A, and is held downward by the constant force ofrubber or other springs k.

Journaled in the standards A, at l, is the shaft L of a presser-bar L,having a hand-lever, 1.

The operation of the machine is obvious.

The inclined table is receded until the knifeedge is in an approximatelyclose contact with the same, when the material is forced under the rolland the presser applied to hold the end of the material close to thetable. The shaft B being then rotated, the knife or saw cuts thematerial exactly, according to the angle of the incline of the table,and this incline may be varied at will by means of the cams I toaccommodate difi'erent thicknesses of leather.

In Fig. 3 is shown a modification of the presser,in which afriction-roll is journaled in a pivoted bar or frame, and the roll bearsupon the material.

Various modifications in details of construction may be made withoutdeparting from the principle or sacrificing the advantages of myinvention, the essential features of which are fully described andshown.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-
